Would you mind disclosing which lender you went with to get 2.0%? Are you paying points? I'm using Better.com for a refi in CA also but the "best" I can get is 2.625% with 0.053% ($330) in closing costs. They don't even list 2.0%
Edit: Better.com is actually listing 2.0% rates but with $9,100 in points, based on my property and location in CA.
